Hi guys,

I need some tutorial on how to configure dns in xsan.
I do not need theory, and found it. I need an ¨how to¨ step by step to configure dns correctly.

And maybe some tips to troubleshooting DNS services.

Thanks
(and sorry for me poor english)

do you have a corporate or on campus dns server? or do you want to setup your own DNS server. I highly recommend using your corporate dns server. if you have one of course

DNS knowledge is power Cool

As abstract has asked, need to know the platform; environment and so on and so forth... In 'theory', it's static IPs all round, no subnet/DNS info plugged into the MDL IP config. IPv6 off all round. Forward (A) and reverse (PTR) records for everything.

I normally use something like "edit1.<acronym for the client>.int" for the Public and "edit1-meta.<acronym for the client>.int" for the MDL.

Depends on what you're using for your DNS.

I will tell you that the theory is important to learn, so that as soon as you get hands on you can apply the information that you've learned.

If you don't know what a dns zone is, or an A, C, PTR, or MX record then you're going to have trouble setting it up. I could tell you to what you need for Xsan, but I can't tell you how that applies to your particular setup. Nor how to name them. I can only give you the guidelines and the theory.

I would suggest looking for some tutorials online. You can google "Mac Server DNS Setup" (If you're on a Mac Server)
I found this one on youtube: http://www.youtube.com/watch?v=OOEgQY9oFK4 Its done by a company that has some other good tutorials on the OS X servers.

I have the theory, and I trie to setup a dns server on xserve for xsan environment, with 4 clients.

I can setup all, and the clients appears work fine, but don´t the xserve.

I have a corporate dns server...

when I run ¨changeip -checkhostname¨ bring me error from dns.

When run the ¨dig¨ command in clients, work fine, but don´t works on me xserve.

I reed and follows this steps... http://labs.hoffmanlabs.com/node/1436

You set the clients IPv4 details to query the Xserves for DNS.. I suspect you forgot to configure the Xserve IPv4 details so that they query themselves?

I setup the the ipv4 details for the xserve...

- ip
- subnet
- gateway
- dns (this is the corporate dns)

Maybe i forgot something...

I setup the dns service, on server admin... as a forward service and put the dns ip from me corporate dns server.

Seems like as good a time as any to repost my DNS Worksheet. When I underline a character, substitute the result of that previous step.

DNS Server A IP address: ________________
DNS Server B IP address: ________________
MDC-A Public IP address: ________________
MDC-A Private IP address: ________________
MDC-B Public IP address: ________________
MDC-B Private IP address: ________________

Contents of DNS in MDC-A's Public Interface in Network Pref Pane: ______________________ (should match a & b with nothing more)
Contents of DNS in MDC-B's Public Interface in Network Pref Pane: ______________________ (should match a & b with nothing more)
Result of dig +short @a -x c: ______________________
Result of dig +short @a -x d: ______________________
Result of dig +short @a -x e: ______________________
Result of dig +short @a -x f: ______________________
Result of dig +short @b -x c: ______________________ (should match 3)
Result of dig +short @b -x d: ______________________ (should match 4)
Result of dig +short @b -x e: ______________________ (should match 5)
Result of dig +short @b -x f: ______________________ (should match 6)
Result of dig +short @a 3: ______________________ (should match c)
Result of dig +short @a 4: ______________________ (should match d)
Result of dig +short @a 5: ______________________ (should match e)
Result of dig +short @a 6: ______________________ (should match f)
Result of dig +short @b 3: ______________________ (should match c)
Result of dig +short @b 4: ______________________ (should match d)
Result of dig +short @b 5: ______________________ (should match e)
Result of dig +short @b 6: ______________________ (should match f)
